Figure 2.5: System Rate: acausal bond graph

The acausal bond graph of system Rate is displayed in Figure 3.4 (on page ) and its label file is listed in Section 3.1.3 (on page ). The subsystems are listed in Section 3.1.3 (on page ).

This component represents rate of reaction equations corresponding to the chemical reaction:

$$\rightarrow$$ (2.1)

The relevant equations are

$$\begin{align}\frac{dc_a}{dt} &= k_a c_a^n e^{-\frac{q_a}{T}} ... ...k_a c_a^n e^{-\frac{q_a}{T}} \tag{Heat of reaction} \end{align}$$

where $\frac{dc_a}{dt}$ is the rate of change of concentration of species A and $Q$ is the corresponding heat generated.
